Dealing With Small & Large Cracks in Residential Concrete Repair Projects
There are concrete slabs which are already cracked and those which are on the verge of cracking. With the right information on your side, you can develop realistic expectations regarding not just the slab cracks but about residential concrete repair as well.
Best Processes for Residential Concrete Repair
There are a number of experts who claim that concrete does not develop cracks if proper procedures are followed.
The proper procedures include compacting and preparing the supporting material under the slab, usage of the right concrete mix, prompt delivery of the mix, professional finishing, curing at the proper temperature and the right amount of moisture.
In any construction project, both time and money need to be invested equally; however, in residential concrete repairs, in order to have crack-free slabs, the right processes must be maintained.
The Three Questions in Residential Concrete Repairs
When evaluating cracks during residential concrete repairs, the following questions need to be asked in order to understand how to deal with them –
- What is the location of the crack?
- How large is the crack, whether it is horizontal or vertical?
- Are the existing cracks causing more cracks in the concrete?
The location of the crack is important.
For instance, if the cracks are in areas which are marked for tile, wood or vinyl floor coverings, then it can have an adverse effect on the cosmetic appeal and performance of such materials.
Vinyl reveals very small cracks.
Cracks which are vertical in nature can lead to the appearance of cracks in the grout and tile as well as cause wooden floors to squeak.
Cracks which run through footings and stem walls are considered to be of a more serious nature when compared to other cracks because they can adversely affect the structural integrity of buildings.
Taking into Account the Size of Cracks
Size is also an important factor when evaluating concrete cracks.
According to the National Association of Home Builders (NAHB), for cracks which are in the interior of slabs and which are 3/16 inch in width or height, residential concrete repairs are required.
State regulators, however, have different standards when it comes to repairing cracks.
Cracks which are smaller can easily be patched- however, this is not a good solution as the patch can become more noticeable than the original crack.
Apart from this, the patching material can itself develop a crack and get dislodged gradually.
For this reason, it is best to let hairline cracks be.
Cracks which are growing vertically, such as those in the patios, driveways and walkways pose to be a hazard.
The best recourse is to bring the wide cracks and those with great vertical displacement to the attention of professionals for evaluation and rectification.
